Specification of Letters Patent.

Application med July 2a, 1910. se'r'iai No. 573,508.'

'To all whom it may concern:

Be it known that I, CHARLES A. Boiconsox, a citizen ofthe United States,and :i resident of San Francisco, 'in the county of San Francisco andState of California, have invented a new and Improved Sprinkler, 'ofwhich the following is a full, clear, and exact description.

This invention relates to a new and improved device for sprinklingllawns` tlower gardens, or the like, which is adapted to distribute aneven shower of water Aas lif'htly as the rain, covering every patch cithe ground surrounding the device within cer tain liinits, varying?Yaccording to the water pressure.

An object of 'this invention vis to provid;` :r device'vhicli will'hesiinpleiu construction,"ineil'iensive to, manufact-ure, strong. durable,and',rclia l)le`in `its: operation.

A` further object'of this invention is to `p'oi-'ide a device in whichthe water is supplied.tangeiitially thereto adjacent the peripherythereof,.and has imparted thereto a eiculaijpiiotion by means of;channels .or passages `within the device, .from .whence *itJ pa.' esfionia central point, where it is -direc ed along. a .divergiug conicalopening, f

which, fby virtue of the circular motion lwhich the stream of water hasattained, =sep 'arates the4 sti-cani into minute particles,-

which' scatter evenly over the adjacent, grou-nd. V

. Tliese'fandl further objects, together with the construction-and`combination of parts, wilkbetmore fu'lli-r descr'het'l hereinafter andpar Icularly seti-forth' in'the claims' Q Reference -is tobe h'adt'o'the `accompany 'ing dra/wings forming ai part of 'this specificatipn,in which' siniilai" characters of reference indicate corresponding partsin all the views, and in which- Figure 1 js a top plairview: Figi'. 2 isa,

horizontal section; and Fig. 3 is awcrtical section on the line 3-f5 ofFig. 2.

Refiring more particularly to the separate arts, 1 indicates acup-shaped casing provi( ed with a bot-toni 2, a1id open at the top.This casingI l'is provided at one side thereof with an inlet hcxtendingrin alineinent. with which there is provided a tubular pi e connection 4.wherebyr the water or Ot ier fluid to be sprinkled is supplied lto thecasing 1.V The pipe vconnection 4 is preferably arranged so as to supplythe water tangentially to the casing 1. This pipe connec tion 4 may' beprovided ivth'anj'lf'siiitable tv pc of hose coupling 5tvlierebyjtinagbeattachedto'a suitable Sup vyatervby means of an intermediate lhoseiepiii'iectiyon. 60

vConnected to the casing@K inlanymvvell lrnown manner, as bybeingfloi'nlipdrintiegralm therewith, or by being soldeteiilierto, thereis provided af partition 6which`forrnswith the vertical wall of thecasingaichannel or passage 7, forming a continua-tion of the pipe 4.This partition Gis-circular inshape, and extends from .one Side:oflthepipe 4 in parallel spaced. relationto tlie1.vertical circular sideof tlielcasing -1,=-to: v. point just. short of itsstartingtpoint.Thisastructure affords acircular passage.rorchannelpin'which the wiliteinhas v impartedithereto' "a cir# cular motion anti-l itreache$=ttlieend0f\the' channel. where; it; opens iu'to'the; inner:cham# 'I5 ber of the casingl, indicated-:IUS: e "f-=l1"` vThe casing1^is providediwithfaz'suituble" .cap or coverg9, which-,is-shownief 'a1eciilar -l0v is spaced apa-rt a slight distance from the hottoniQ, andis adaptedt'opermit Vthe Water from ,the 'sprinkling' device al'itl'rotate l'on' 90- .-the outwardly-diverg'gfi'n'gI sides of 'the faunamonth, Iso that the stiear'n 'of 'waterjs broke' t up intoivery'smallIilltlicllenv on lall sides of the;4 eviee `tliiis`pro. vidinglinvaton'iizing rci'intrat .io'zuzlle'f` l z.V y 95 z The various partsofjtliis device may tbe made of any suitable material, and. maybe..connected togetlier in any suitable manner.

.It is preferred, however,that.V tfllie.passage-` T,- 'formed betweenthe partition .6- andtlielside l100 of the casng'l, be constructed ofsomewhat greater size .than the hose,i$o .that'xthere Will-v he no backpiessureonthe hose. a. A ny suitable` type of stand Eonbase maybe lprovided for this device; so. that-,it can-M1105 set on the lawn ortower..garden, and moved? f rom place to place, according 'tothe..poin.tj; which it is desired to.s1'n1in`kle..- -1

The operation of the device wil be readil understood when taken inconnection wit 11o" the abovede:"ription. The sprinkler is com nectedbylmeans of a hose coupling 5, to any suitable length 'of hose, which inturn is connected to a suitable supply of water under a head. The waterentering under a head in the pipe llis directed tangentially in thepassage T, Where it, has imparted to it a circular motion, which motionit retains on entering the chamber` 8. The stream oi water circulated atav considerable speed comes to the outlet 10,1yl1ere it is delie'etedalong the diverging sides of the outlet mouth formed by -the funnel 9,so lila( it is broken up into a fine spray, which is distributed evenlyon all sides of the sprinkler, and over a radius depending-on thepressure of ib'e water.

It will thus be seen that there 1s provlded a, sim le. and efficient srinklin'el device`4 whielnnnlike the ordinary screen sprinklers1 willnot clog up. as the ouelt opening l0 is oi' suiiieient size to permitalmost any particles which may enter tlie'deviec to pass out durin thesprinkling:r operation.

Vhlle I have Shown one embodiment of my invention, I do not wish to belimited to the 'specific details thereof, but desire to be protected' 1nvarious changes, modifications and alterations which may come \\'1tlnnthe scopeof the appended claims.

-liaving .'thus described my invention, l

.claim as new and desire to secure by Letters Patent v1. A Sprlnkler,comprislng a casing: hav` ing al, atbott-om with sides perpendicularing' with said botlorrr and said sides a cham-V ber of' right-angletriangular cross section, and a spiral proeelion dividing' said chamberinto inner and outer portions, whereby a eil-cular motion is imparted totlxewater admilled' thereto.

'2. A sprinkler, comprising a cylindrical :singA open at the top andhaving a flat bottom7 a remo 'able cover for 'said easing, havingrascrew-Lineaded connection therewith, `said cover being in the form ofan inverted eoniral horn having an outlet at the apex thereof, said apexbeing located adjacent said bolt-om, means' for supplying water to saidcasing adjacent the periphery thereof, and a pariilion extending fromsaid .means 'in a circular manner within said easing, nia-why a circularmotion is imparted to :he water admitted to Said casing.

l n testimony whereof I have signed my name to this specification in-the presence of luo subscribing witnesses. 4
